IMPROVEMENT IN VENTILATING ATTACHMENTS FOR WINDOWS.

Specification forming part of Letters Patent No. 182,484, datedSeptember 19, 1876; application filed January 19, 1876.

To all whom it may concern:

Be it known that I, CHARLES CARROLL SANKEY, of Newcastle, in the countyof Lawrence and State of Pennsylvania, have invented a new and ImprovedVentilating Attachment for Windows; and I do hereby declare that thefollowing is a full, clear, and exact description of the same.

This invention has relation to casementventilators for the Windows ofapartments; and it consists in the construction and novel arrangement ofthe side walls and their attachment hooks and bolts, the transparentfront and the extended top and base laterally notched to fit themoldings of the windowframe in rear of the sash, as hereinafter shownand described.

In the accompanying drawing, forming part of this specification, Figurel is an elevation of a window casing provided with my improvedventilating attachment; Fig. 2, a vertical section of the same on line00 m, Fig. 1; Fig. 3, a cross-section on line 3 y, Fig. 1, showing theventilator in plan 5 .Fig. 4., a side elevation of the ventilatordetached.

The Window-casing A and sliding sash B are of the usual construction.The ventilator C has a horizontal top, a, and a vertical, or nearlyvertical, front, I), and ends a. The same is made, preferably, of abouthalf the height of the lower sash, and is so constructed as to adapt itto fit closely against and between the sides of the casin g A. In orderto accomplish this, the top a and bottom 2 of the ventilator areextended horizontally forward beyond the vertical edges of the sides,and are notched, as shown at c, on each side to lit the moldings of thewindow-casing closely, and to project between the same to the sash B,against which, when the window is open, the top a fits neatly. The edges0' of the sides 0 are designed to fit against the face-moldings D, inorder that the span of the ventilator will be equal to that of thewindow when the sash is raised. The extended bottom a affords a broadbase for the support of the ventilator. The means of attachment arehooks e, fitting in slotted plates f affixed to the casing, and

hand-bolts h, which may be slided into sockets in the casing when theventilator has been adjusted in place. Said bolts must therefore bewithdrawn before the ventilator can be raised and detached from thecasing, thereby providing protection against thieves. The front b of theventilator is formed, wholly or in part, of a transparent plate, so thatthe entrance of light, and the ordinary view from the window, may not beobstructed. The top a has a large opening for the admission of air. Thismay be provided with a netting to exclude insects, &c., when occasionrequires.

The lower sash B being raised, as shown, the fresh air will enter theapartment, taking the course indicated by arrows, to wit: striking firstagainst the front b, and passing thence upward through the open top a ofthe ventilator toward the ceiling of the apartment.

The chief advantages of the ventilator over others of its class are thesecurity of the attachment to the window-casing, and the facility withwhich it may be detached when occasion requires; also, the fact that itofi'ers the slightest possible obstruction to the view from the windowand to the passage of light into the apartment; also, that the fiat topmay be utilized as a flower-stand or support without thereby sensiblyaffecting the air-currents.

What I claim is 1. The casement-ventilator for windows consisting of theglass front I), the sides 0, opposite the face-molding of thewindow-casing, and cut away at c to fit the same, and the top a and base2 laterally notched to correspond with the moldings, and extendingbeyond the sides to meet the sash, substantially as specified.

2. The combination, with the slotted and perforated molding D, of thecasement-ventilator, having the horizontally-extended top, and the sidescut away at c to fit said molding, and the sliding hooks andlocking-bolts, substantially as specified.
